Small autohelms

busy home [deleted] says:

According to a good friend with a Seamaster who is a electro mechanical engineer the autohelm is very dependant on a full 12 v
at all times He has heavy wireing to his and has much more power now. Worth the effort

On my raymarine ST1000 I have run 15 amp cable fromthe battery to the socket as recommended, I never really understood why as the drain is so small according to the specifications, and only assumed that the thicker cable was incase you were plugging in all the extra toys that it is compatible with. However it now makes more sense from what you have said Ron.
Having said all this really if the boat is balanced properly with the sails the autohelm should only require very little input to keep on course.
Are you going to use your windvane on Goskar ron?

In normal conditions the load is nt heavy but as seas build up loads are heavier Chilles autohelm 1000 sometimes struggles .
I have bought a Navico tp 32 for goskar (ebay) In fact I bought two !
I dont know about the wind vane it may hinder getting onboard .I have not got a stern ladder and might go alongside in the dingey and use pelecan hooks on guard wires. It may be difficult for Sue to climb over stern! I do like the idea of silent steering though ! We willsee!

I reckon it wouldn't be too hard to design a windvane that bolts to the pushpit and connects directly to the helm, rather than the very elaborate contraptions that bolt onto the stern and down to a secondary rudder, it after all is relatively simple technology based on old designs , the problem would be to get the gearing right and developing a feathering system to smooth out gusts.

That is exactly what the system I built does, It has no paddle /oar
assy i.t ,pulls the tiller as the wind blows the vane over via precise gearing and weighed feedback It was developed over three year circum navigation . Unfortunatly it only works on a light displacment
boat with good directional stability ie the Achilles Thats why i choose it .
The servo rudder systems are mmmuch more powerfull as the oar twists and devolops huge forces ie as in sculling!
Hasler was the man ,who devoloped the servo system. for the 1962
race against Chichester who used Miranda a wind only system but had to be reefed down etc Most lone sailers then used the hasler .
The windvane I built was more an experement than a serious thing.
I think a good solar panel will be high on my letter to Santa

Blast I thought that i had come up with an original idea and was going to be able to retire. I have just ordered a book from Amazon which is described as the definitive manual for windvane steering systems detailing how they work different sorts and a DIY design. (probably the one you have).

My solar panel was around £60 on E bay and delivers a measured 18 volts in my conservatory. I don't need to remind you to buy one with a built in diode or when it gets dark the power will drain right back out of your battery.

Will it damage that lovely name on the back of Goskar when you fit it?
I detect some rivaly creeping in between Goskar and Chille.... Have you finished the windows yet? This will be the next ig job on Aeolus as mine are getting quite badly cracked & crazed

By the way the book that i have ordered is "The Windvane Self- Steering Handbook" by Bill Morris

Possibly will cover it a bit But ican remove and start again if neccessary .
Not rivalry but I have learnt a lot from sailing on Chille,
sailing 10 /10 comfort 2/10 boarding difficult from a beach berth,
in a chop as you experenced ,I will be widening the cockpit seats to accomodate my broad posterior .making the step slide in to be able to stand up in companion way .Removed shelves to allow my shoulders room when sitting sideways on my new lengthways seat
(feet up)! Making lee cloths to keep stuff from falling on floor as soon as heeled.etc etc.. Windows are cut to shape and rounded off.
They will be stuck on with sikaflex 295 uv only NO SCREWS .current practise on super yachts Started measureing up for new trailer this morning,

Skykomish E29 says:

Thats interesting how will you hold the perspex in place whilst the siklaflex sets as there is quite a curve on the window or are you going to pre shape it by heating up first?

So is this a new log trailer or one for Goskar? i am sure Viv will be pleased to get her caravan back or at least the chassis!

busy home [deleted] says:

Hot glue L shape blocks onto cabin and use little wedges to press perspex down (in theroy),
Vivs chassis is now a log trailer the caravan is the tearoom! Mark and Viv will have to borrow my motor home and rough it!
This a road trailer for Goskar the same design as Mr Currys 303.
